To keep your work for future use, you must give the document a name and save it. After you save it, the document is available each time you want to use it.
It's best to name and save a document soon after you start working on it. After that, it's a good idea to frequently save drawings or diagrams as you work. You should also be sure to save any template files that you change.
You can print your drawings by choosing a menu command or toolbar button.
